I'm gonna be building a very similar system to you, looks good but trust me if you're playing any games or really running any kind of intensive graphical software you're gonna want a graphics card... the on board graphics just cant compete..
Thanks for your reply! I can install another Graphics card in Mother Board which I bought, correct? Right now, I don't have any much ideas to play games.
Also, what is this Arctic cooling? Do I need that cooling component?
